Water Source
Colorado River via Lake Mead. SNWA draws the vast majority of its supply through intake structures reaching deep into Lake Mead, which explains why the mineral content is so consistent across the entire Las Vegas Valley.
Managing Authority
Southern Nevada Water Authority (SNWA) treats and delivers water for Henderson and the rest of Clark County. It sources from the same Lake Mead intakes that serve Las Vegas and North Las Vegas, so households in Green Valley see essentially the same hardness reading as Lake Las Vegas.
